Canadian farmers are constantly balancing opportunity and challenge. Each season brings its own conditions, sometimes favourable, sometimes testing, and success depends on making the right decisions for the land, the crops, and the years ahead. Indeed, it’s often remarked that farming is 10% management, 90% weather. This adaptability has always been at the heart of Canadian agriculture.
There is an opportunity to build on that adaptability with a practical tool that supports crop performance, strengthens soils, and delivers lasting environmental benefits. Enhanced rock weathering (ERW) is a nature-based approach that works with existing farming practices to deliver agronomic gains and measurable carbon removal, helping Canadian agriculture stay productive and resilient for decades to come.
Stronger Crops, Healthier Soils
ERW involves applying finely crushed silicate rock, such as locally sourced wollastonite, to farmland. As the rock naturally weathers, it releases minerals that benefit crop growth and soil function. At the same time, it reacts with carbon dioxide from the air, locking it away in a stable mineral form for hundreds of thousands of years.
For farmers, the first impact is seen in the field:
– Greater crop resilience: Silicon from wollastonite strengthens plant cell walls, helping crops tolerate pressures from pests, disease, drought, and heat stress.
– Improved nutrient use efficiency: Balanced soil chemistry allows plants to make better use of available nutrients, reducing losses to leaching or runoff and supporting stronger growth.
– Long-lasting benefits: Wollastonite can help stabilise soil pH, often with effects that last multiple seasons, reducing the frequency of corrective applications.
Proven Results in Canada
On farms in Ontario, wollastonite-treated fields have shown more even stands, stronger plants, and improved kernel fill in grains compared to untreated areas. In some cases, farmers have been able to reduce lime applications in the following seasons.
Because wollastonite can be applied using standard lime or fertiliser spreading equipment, it integrates easily into existing farm operations. Application can be timed before or after harvest to fit around the growing season without disrupting other fieldwork.
Working Alongside Existing Practices
ERW is designed to complement the work farmers are already doing to care for their soils. For those investing in practices such as crop rotation, cover cropping, and reduced tillage, wollastonite offers another way to enhance resilience and productivity.
It’s also a practical, low-barrier option. In the UNDO Farmers program, the wollastonite itself is provided at no cost, with only trucking to cover, and in many cases, that cost is subsidised. The result is an accessible way to strengthen farm performance while delivering environmental benefits in the background.
The UNDO Farmers program
UNDO works directly with farmers as partners, not as customers. Unlike a traditional input supplier, we don’t sell rock by the bag. Instead, program members gain access to:
1. Free soil testing and monitoring
We take soil samples before spreading and share the results, giving farmers clear insights into the long-term impacts on their land and crops.
2. Professional application at the right time
Wollastonite is applied at 2–4 tonnes per acre using standard lime spreaders. We follow the Canadian spreading season, with peak operations in spring, summer, and fall, and schedule applications to protect healthy, intact crops.
3. Affordable, accessible input
The wollastonite is provided free of charge. Farmers only cover trucking, which is often subsidised, making it a cost-effective alternative to inputs such as lime or synthetic fertilisers.
4. Local, low-impact sourcing
Eligible farms are within 200 – 250 km of our partner site in Ontario. This keeps transport distances short, reducing emissions and ensuring cost efficiency.
Our program gives farmers the agronomic benefits of wollastonite while UNDO manages the carbon removal process, tracking results and ensuring benefits are measurable and impactful.
How Carbon Removal Works On Your Land
As wollastonite weathers in the soil, it reacts with carbon dioxide in rainwater and soil moisture, transforming it into stable carbonate minerals. This process is a natural part of the Earth’s carbon cycle, but in nature, it takes thousands of years. By crushing the rock and applying it to agricultural land, weathering happens much faster, so carbon is removed from the atmosphere within years rather than centuries.
While this carbon removal happens quietly in the background, the immediate, visible benefits are seen in the soil and crops. Farmers adopting ERW are building resilience into their operations while contributing to a more stable environment for agriculture.
Measured and Impactful
UNDO’s ERW projects in Canada are backed by rigorous measurement techniques. Soil and water samples, laboratory testing, and modelling track both the agronomic results and the carbon removal achieved.
Our Sentinel Sites, dedicated research plots, collect high-quality scientific data under active farm conditions. This data helps refine best practices and gives farmers reliable, transparent information about how wollastonite performs in Canadian soils.
Positioning For Future Opportunities
Demand for high-quality, durable carbon removal is growing. Businesses and organisations are seeking solutions that store carbon for the long term and are backed by robust evidence.
Joining the UNDO Farmers Program now means being part of a leading group of producers with strong results, trusted measurement, and a clear role in the future of sustainable agriculture.
Strengthening The Future Of Canadian Farming
Resilient soils are the foundation of resilient farms. By improving nutrient availability, enhancing crop strength, and maintaining balanced soil chemistry, ERW supports the productivity and profitability that Canadian agriculture depends on.
At the same time, the carbon removal achieved helps protect the environmental stability needed for reliable growing conditions. Farmers in the UNDO program are proving that productive agriculture and environmental stewardship can go hand in hand, and that Canadian farms can lead the way in delivering both.
Build long-term resilience for both your farm and the environment
By joining the UNDO Farmers program, you can strengthen your land today, prepare for the seasons ahead, and leave a lasting legacy for the next generation of Canadian agriculture.
